lM PROVEMENT IN CHlN-ADJUSTERS.

Specification forming part of Letters Patent No. 204,487, dated June 4,1878 application filed March 1, 1878.

To all whom it may concern Be it known that we, RoBERT S. GANOUNG andWILLIAM H. LANGDON, of Seneca Falls, in the county of Seneca and Stateof New York, have invented a new and useful Improvement inChin-Adjusters, which improvement is fully set forth in the followingspecification and accompanying drawing, in which- Figure 1 is aperspective view of said chinadjuster with our improvements attached.Fig. 2 is a sectional View of the tube, show in g the spring engagingwith the ratchet-bar.

The object of our invention is to form a support which can be easily andquickly adjusted to the chin to keep the same in a natural positionafter death until the body becomes cold and the jaw fixed.

' In the drawings, E E are two triangular concave disks. One supportsthe chin, and the other rests on the collar or band of the shirt orgarments. The disks are made triangular and concave, for the purpose offitting the under side of the chin. ()ne of the prongs of the disk fitsin the crotch of the jaw, while the other two fit outside of the jaw,thus preventing the chin from falling or slipping in any direction. Theother disk, also, on account of its shape, will not slip off thecollarband.

The disk E is secured to a rod, 0, which is provided with a line ofangular teeth or a ratchet, D. The disk E is fastened to a hollow tube,

B. To the periphery of the tube B is attached a spring-pawl, A, which ishook-shaped at its extremity, and made to enter a slot, b, formed insaid tube.

To use the adjuster, place either one of the disks in its properposition in the neck, and raise the other disk until it rests under thechin; then turn the rod or bar slightly, bringing the ratchet in a linewith the slot, whereupon the spring will instantly engage with theratchet, and hold the adjuster firmly in its proper position. When it isdesired to remove the adjuster, it is only necessary to turn the rodback or forward until the pawl and ratchet are disengaged, when the rodwill be lowered in the tube and the adjuster removed.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

In a chin-adjuster, the combination of the ratchet-bar 0, provided witha disk, E, and the slotted tube B, provided with a disk, E, and aspring-pawl, A, working in the slot of said tube, substantially asdescribed, and for the purpose specified.
